They look and behave like normal rubber bands when stretched. But when removed from whatever they are holding, they instantly spring back into their original Rock Band shapes! Packaged in a plastic bag. The Hottest Thing since the Pet Rock! Worn as Bracelets, Traded & Collected by all Ages. But you can enjoy them too. Flick them at your co-workers, use them for wrapping presents or horde them all for yourself. What a great gift for students or parties. These are a favourite for magicians and parties.
